Definitions
- This invention relates to an oral composition comprising low levels of perlite.
- abrasives in oral compositions such as toothpaste is well known.
- the abrasive has a cleaning as well as a polishing/whitening benefit.
- the removal of tartar from the tooth surface is thought to reduce the incidence of caries.
- Dental Practitioners recommend that tartar removal should be exercised professionally at least twice a year, preferably more but it is recognised that the build-up of tartar can be reduced by effective brushing of the teeth.
- Typical abrasives used in toothpastes include silicas and chalk, however, the prior art also discloses the use of perlite in toothpaste formulations.
- EP-B1-0 268 763 (Hawe-Neos) describes a dental care medium for prophylactic dental hygiene comprising perlite and a synthetically produced precipitation silicic acid.
- US 5 266 304 (Baffelli) describes dental care and cleaning composition in a water-free part containing at least 40% by weight of perlite as a sole and combined cleaning and polishing body.
- US 5 597 553 (Baffelli) describes a toothpaste comprising as an abrasive, preferably as sole abrasive, expanded perlite, generally with a particle size in the range of 1 to 150 ⁇ m, in particular with main fraction in the region 20 ⁇ m.
- the perlite is comprises from 1 to not more than 15% by weight of the composition.
- the abrasivity of a toothpaste is measured according to a protocol described in the journal of Dental Research (1976) 55(4), 563. This describes how the Relative Dental Abrasion (RDA) and Relative Enamel Abrasion (REA) are evaluated.
- RDA Relative Dental Abrasion
- REA Relative Enamel Abrasion
- a toothpaste will be capable of cleaning the teeth without wearing down the tooth enamel and dentine. So while it is necessary to have a cleaning efficacy a toothpaste with too high an RDA is undesirable.
- PCR Pellicle Cleaning Ratio
- perlite is a natural product and while it is purified to a reasonable degree before incorporation into an oral care formulation it still comprises impurities. These impurities are usually of a grey colour and introduce speckling of the formulation. This is particularly noticeable where the product is a white paste. Again, this is seen as a significant consumer negative.
- a further disadvantage of high levels of perlite is that it behaves as a catalyst for the degradation of flavour ingredients, particularly in products where the pH is relatively high, e.g. in oral compositions comprising bicarbonate. This is a clear disadvantage for the consumer but is also unacceptable for the manufacturer as the cost of the flavour often accounts for the bulk of the raw materials costs. It is also known for high quantities of perlite to cause syneresis of typical dentifrice formulations.
- perlite can be incorporated as a cleaning agent in smaller amounts than is disclosed in the prior art, while still providing an effective cleaning benefit. Further the abrasive effect of the reduced levels of perlite also provide for a greater cleaning/polishing with respect to abrasivity then higher quantities of perlite, i.e. the PCR substantially maintained or reduced only partially, while the ADR is significantly reduced by using smaller amounts of perlite.
- the invention provides an oral composition comprising from 0.01 to 0.9% by weight of perlite.
- the composition according to the invention comprises from 0.1 to 0.8% and especially from 0.3 to 0.7% by weight of perlite.
- Perlite is a naturally occurring sodium/potassium/aluminium silicate and is available commercially from Seitzfilterwerke as Perlite C; from Elfatochem as Ceka Flo MA/P/2A/R; and from World Mineral as Europearl 475/900S/E50.
- a preferred perlite comprises particles of average size below 300 and preferably below 200 ⁇ m in diameter. It is understood that the size reference to diameter is approximate as the particles are of random shape and not necessarily spherical. If a sample comprises larger particles of perlite it is preferred that the sample is sieved through a suitable gauge before being included in the formulation.
- composition according to the invention may be any oral, non-food composition, e.g. toothpaste and may be in the form of a gel, paste, gum or any other suitable type.
- composition according to the invention may also comprise ingredients, which are common in dentifrices.
- ingredients which are common in dentifrices. Examples of such ingredients include:
- the oral composition may also be in any of the product forms common in the art, e.g. dentifrice (gel or paste), lozenge, chewing gum etc.
- the following table shows the PCR and ADR of typical dentifrice formulations comprising varying levels of perlite.
